Walking makes her giggle

Just before nap today Megan was in our room with Will (that is where she went after climbing the stairs).  After I put Sam down I went to see what they were up to and Megan walked from Will to me.  We try to take advantage of any opportunity when she initiates walking so we stood there and she walked back and forth between us several times.  

She was so excited and happy that each time she would leave one of us and start walking she would start giggling and laugh so hard that she would throw her head back with glee.  She had all of us laughing to the point she had to stop walking because she just couldn't make it more than a couple of steps without knocking herself over.
